🔍#CancerImmuneEscape
Hey there curious minds! 🧠 Have you ever wondered how cancer cells pull off the ultimate disappearing act from our immune system? 🤔 It’s like they’ve got some serious escape artist skills! 🎩🐇
The human body is like a fortress, constantly on guard, identifying and destroying cancer cells left and right. But somehow, those sneaky cancer cells manage to slip through the cracks and wreak havoc. 🦠🔍
So, how exactly do these cancer cells outsmart our immune system time and time again? Do they have some sort of secret hideout where they plot their next move? 🕵️♂️ Or do they just grow to a certain size that makes them invisible to our immune defenses? 🤷♀️
Let’s unravel this mystery together! 💡 Share your thoughts, insights, and maybe even a theory or two in the comments below.

Survival of the fittest. Immune system generates selective pressure for cancer cells that are adept at avoiding immune system.
There are many different mechanisms to achieve this. Most fundamental one is shutting down the intrinsic emergency system. Normally, once a cell senses that there is something wrong with its cell cycle, it initiates apoptosis. If this system also fails, it release chemical signals to fetch immune cells to initiate apoptosis for it, or it kill it directly.
Next line of defense is the cells surrounding the cancer cells. If these cells sense unusual behavior, they will rat out the cancer cell to immune cells. But cancer cells also develop mechanisms to suppress this system.
There are other backup mechanisms, but cancer cells basically accumulate mutations selected by the selective pressure immune system generates.
